Global Warming

The Earth is warming and human activity is the primary cause. Climate disruptions put our food and water supply at risk, endanger our health, jeopardize our national security, andthreaten other basic human needs. Some impacts—such as record high temperatures, melting glaciers, and severe flooding and droughts—are already becoming increasingly common across the country andaround the world. So far, our national leaders are failing to act quickly to reduce heat-trapping emissions.
However, there is much we can do to protect the health and economic well-being of current andfuture generations from the consequences of the heat-trapping emissions caused when we burn coal, oil, and gas to generate electricity, drive our cars, and fuel our businesses.
Our country is at acrossroads: the United States can act responsibly and seize the opportunity to lead by developing new, innovative solutions, as well as immediately putting to use the many practical solutions we have atour disposal today; or we can choose to do nothing and deal with severe consequences later. At UCS we believe the choice is clear. It is time to push forward toward a brighter, cleaner future.Global Warming Impacts

To realize the urgency of global warming, it’s important to understand the ways it affects us. Sea levels are rising and glaciers are melting; record high temperatures andsevere rainstorms and droughts are becoming increasingly common.
To help understand the problem and find practical solutions, UCS scientists assess the effects of climate change both across the globeand in our own backyard.
In this section, explore the connections between the climate data we have and the changes we see around us—and those we expect to see in the future—from overall trends tospecific regional impacts.

Global Warming Contrarians

The overwhelming consensus among climate scientists is that global warming is real, primarily caused by human activity, and a serious...
